FJ2912C is capable of creating a seal across a wide range of gasket stress. This makes the product suitable not just for use in standard metallic flanged connections but also in load compromised bolted connections; such as those applications involving glass lined, plastic and thin or distorted metal flanges. Sigma® 500 material is inherently clean, making it suitable for use in industries where product contamination may be of concern such as food, beverage and pharmaceuticals. Suitable for sealing most chemicals across the whole pH range (0-14) with the exception of molten alkali metals, fluorine gas, hydrogen fluoride or materials, which may generate these.
